TRANZX is a manufacturer of high end bike components, and produces a range of quality indoor trainers. It's produced by JD Corporation

The JD111 indoor trainer uses Magnetic resistance allowing it to be smooth and very quiet, it is a great performing, excellent value trainer for those who are serious about stationery trainers. Ideal for working out at home or warm up before a race. The resistance is adjustable via a handlebar mounted lever offering you 6 levels of resistance to recreate real cycling conditions, or levels of intensity for target training.

I'm not at my PC with the software right now, but go to the rollers and pick one of resistance settings, say 1 or 2 if they go from 0 to 3. From there you can tweak up or down by using coefficients tab as I described previously.
